Abstract

In this paper, relative position control problem in rendezvous and docking (RVD) is studied. Based on CW equations, its state-space form is deduced and a state feedback robust controller is designed by using H_∞ control theory for this problem. Considering spacecraft thruster engines, PWPF modulator is used to modulate continuous signals to pulse sequence to adapt to practical situation. Simulation of closed-loop system is undertaken with disturbance added in. Result shows the controller is robust and feasible for spacecraft RVD.
